I rewrote a bit of Smokeping.pm to scale the graphs logarithmically. So they can't start at 0, even if I wanted them to. :) Unfortunately that means that the lower end of the scale now has to be calculated, or at least chosen based on the data. There's a findmax() function in Smokeping.pm already, I added a function findmin() so that scale ranges give reasonable positioning of the average lines on the plots. Alternatively I just choose some arbitrary value like 100 microseconds or 1 millisecond, but that sometimes leaves the graphs looking cramped. It does well enough for my purposes but it could certainly be improved. http://www.jubileegroup.co.uk/JOS/misc/Smokeping.pm Here's the version that I used to find out what was going on: http://www.jubileegroup.co.uk/JOS/misc/Smokeping.with.logging.pm I think these are based on version 2.003006 (I can't remember if I grabbed the Debian version or if I used the original) so you might need to make some allowances for that. > Asking a lot of questions lately, but we are putting a big push on > getting Smokeping up and running as a production tool. If you're sufficiently familiar with the underlying tools and protocols you should have it up and running in a couple of hours, although you might not cover your entire network at the first try. Then it's just a matter of editing the configuration files to add more machines. If there are special requirements in your situation, perhaps you should share them on the list? I'm sure you'd get useful feedback. -- 73, Ged. _______________________________________________ smokeping-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/smokeping-users
